305-046-500-558

Edgeboard Connectors Overview

The EDAC Inc. 305-046-500-558 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 46 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). It utilizes gold-plated copper alloy contacts and a green thermoplastic insulator body. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design for secure board retention
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Low-profile insulator body accommodates space-constrained applications
• Thermoplastic housing provides structural stability and environmental protection

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted connections
• Communication equipment utilizing standard thickness PCBs
• Consumer electronics with high-density interconnect needs
• Medical devices demanding reliable electrical interfaces

Edgeboard Connectors Procurement Notes

Verify that the target application requires a dual-edge connector configuration, as this part is not compatible with single-edge boards. Confirm the PCB thickness matches the specified 1.57 mm nominal requirement to ensure proper mechanical engagement. Check regional availability constraints, as distribution channels may indicate limited stock or shipping restrictions in specific territories. Ensure RoHS compliance requirements are met if the end product mandates restricted substance regulations.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount interface is required for double-sided edge cards. The 3.96 mm pitch suits applications where standard board layouts align with this spacing. Consider the 5 A current rating against the total load of connected circuits. The gold plating is suitable for environments where corrosion resistance is critical. Evaluate the operating temperature range against the expected thermal profile of the installation site.

Edgeboard Connectors Part Context

This model belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its use of thermoplastic housings and gold-plated contacts. It is distinct from the 345 series, which typically uses wire wrap termination, and the 355 series, which may feature different row spacings. The 305 series is widely used in industrial and commercial sectors for its durability and standardized dimensions.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical position counts and pitch, such as the 305-048-500-558, though position differences must be accounted for. Verify that any replacement maintains the 3.96 mm pitch and 1.57 mm board thickness compatibility. Cross-reference with other manufacturers' offerings only if they explicitly match these dimensional and electrical specifications.
